Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a perspective view of the fire hydrant device 1 of this embodiment, and FIG. 2 shows a perspective view of the fire hydrant device 1 with the hose holder 11 pulled up to the upper end position. As shown in FIG. 1, the fire hydrant device 1 of this embodiment has a box-shaped main body 10, inside which a fire hose 12 having a nozzle 13 at the tip, valves including a fire hydrant valve, etc. are installed. It is stored. A door 30 that can be opened for maintenance or the like is provided on the front surface of the main body 10.

In the event of a fire, as shown in FIG. 2, by pulling up the hose holder 11 housed in the main body 10, the fire extinguishing hose 12 held in the hose holder 11 can be pulled out to extinguish the fire. . The fire hose 12 has a nozzle 13 at its tip.

The hose holder 11 includes a box-shaped hose storage section 20 that can store the wound fire hose 12, an upper surface section 21 that constitutes the upper surface of the fire hydrant device 1, and a section that is housed within the main body section 10. It has support portions 22 provided at the four corners. FIG. 3 shows a front view of the fire hydrant device 1 with the hose holder 11 pulled up to the upper end position, and FIG. 4 shows a rear view of the fire hydrant device 1 with the hose holder 11 pulled up to the upper end position. are shown respectively. The hose storage section 20 has a front opening 20a on the front side for pulling out the fire hose 12. The hose storage section 20 also has a back opening 20b on the back side for pulling out the fire extinguishing hose 12. The back opening 20b is formed at a lower position than the front opening 20a.

FIG. 5 shows an explanatory diagram of the fire hydrant device 1 of this embodiment installed in a tunnel. The tunnel has a lifeguard passage 61 on the side of the road 60. The guard passage 61 is formed along the length direction of the road 60 to have a height of about 1 m. The fire hydrant device 1 is installed so as to be embedded in the lifeguard passage 61. The fire hydrant device 1 installed in the lifeguard passageway 61 has an upper surface portion 21 that is substantially flush with the upper surface of the lifeguard passageway 61 . Therefore, it is possible to prevent the fire hydrant device 1 from interfering with traffic in the lifeguard passage 61 during normal times.

In the event of a fire, the hose holder 11 protrudes upward as shown in FIG. is also exposed upwards. In this state, the fire hose 12 can be pulled out from the road 60 through the front opening 20a. Moreover, the fire hose 12 can be pulled out from the observer passage 61 via the back opening 20b. As described above, the fire hydrant device 1 of the present embodiment has a structure in which the hose holder 11 is pulled upward from the main body 10, thereby opening the front opening 20a of the hose storage section 20 in which the fire hose 12 is stored. and the rear opening 20b are exposed. Therefore, when the fire hydrant device 1 is installed so as to be embedded in the lifeguard passage 61, the fire hose 12 can be pulled out from both the road 60 side and the lifeguard passage 61 side. In particular, even if a car is stopped in front of the fire hydrant device 1, the fire hose 12 can be reliably pulled out because the hose holder 11 is pulled up relative to the main body 10.

Next, the structure for pulling up the hose holder 11 will be described in detail. FIG. 6 shows a longitudinal cross-sectional view of the fire hydrant device 1 cut near the front. As shown in this figure, a hose holder 11 housing a fire hose 12 is housed in the main body 10, and the main body 10 has a drive unit 31 for raising and lowering the hose holder 11. ing.

The drive unit 31 includes an elastic drive member 32 fixed to the main body 10, a wire 33 that connects the elastic drive member 32 and the hose holder 11, and two pulley members 34 and 35 on which the wire 33 is hooked. has been done. The elastic drive member 32 is a spring member that biases the wire 33 in the direction of pulling when the hose holder 11 is housed in the main body 10, and is a Conston spring. The Conston spring generates a constant biasing force within a predetermined stroke range. The elastic drive member 32 is not limited to the Conston spring, and other types of elastic members may be used.

A wire 33 extending upwardly from the elastic drive member 32 is deflected horizontally by a pulley member 34 and further downwardly by a pulley member 35 . The wire 33 is connected and fixed at its lower end to a wire fixing part 25 formed at the lower part of the hose holder 11. Since the elastic drive member 32 biases the wire 33 in the pulling direction, the hose holder 11 to which the wire 33 is fixed at the bottom is biased in the upward direction.

A buffer member 27 is provided on the inner lower surface of the main body portion 10 so as to come into contact with the lower end portion of the hose holder 11 . The buffer member 27 is made of an elastic member such as rubber, and when the hose holder 11 that has been pulled upward is stored in the main body 10, it comes into contact with the lower end of the hose holder 11, thereby absorbing the impact. can be alleviated. Further, a buffer member 28 is provided on the inner upper surface of the main body portion 10 and can come into contact with the lower end portion of the hose holder 11 when the hose holder 11 is pulled up. The buffer member 28 on the upper part of the main body 10 can cushion the impact by coming into contact with the lower end of the hose holder 11 when the hose holder 11 is pulled up to the upper end position. Note that the buffer member is not limited to this configuration, and for example, a damper or a shock absorber may be provided between the main body portion 10 and the hose holder 11.

As shown in FIG. 1, a lock release portion 24 is provided on the upper surface portion 21 of the hose holder 11. As shown in FIG. The lock release part 24 is linked with the lock engagement part 23 that is engaged with the main body part 10. Since the lock engaging portion 23 engages with the main body 10, it maintains a state within the main body 10 against the biasing force of the elastic drive member 32. When the lock release section 24 is operated to push up, the lock engagement section 23 linked to the lock release section 24 is released from the engagement state with the main body section 10 . When the engagement state of the lock engagement portion 23 with the main body portion 10 is released, the hose holder 11 is pulled upward by the wire 33 due to the biasing force of the elastic drive member 32. The biasing force of the elastic drive member 32 is set to be greater than the weight of the hose holder 11 housing the fire extinguishing hose 12. Therefore, the hose holder 11 whose engagement state of the lock engagement portion 23 is released is automatically pulled upward only by the biasing force of the elastic drive member 32.

Although the upper surface portion 21 of the hose storage portion 20 has a smooth surface in the drawing, it may be made of a striped steel plate and have an uneven surface. Since the upper surface portion 21 is flush with the observer passageway 61, the unevenness of the upper surface portion 21 can prevent workers walking on the observer passageway 61 from slipping.

The lock release part 24 is arranged at the center of the upper surface part 21 in the left-right direction. Therefore, when the lock release section 24 is operated to release the stored state of the hose holder 11, the hose holder 11 can be pulled up in a well-balanced manner.

A first nameplate part 21a and a second nameplate part 21b are arranged on both sides of the upper surface part 21 with the lock release part 24 in between. On both the first nameplate part 21a and the second nameplate part 21b, figures and characters explaining how to pull up the hose holder 11 are displayed. The first nameplate part 21a faces the front side of the main body part 10, and the second nameplate part 21b faces the back side of the main body part 10. Thereby, the nameplate portion can be confirmed from both the road 60 side and the lifeguard passageway 61 side.

The first nameplate portion 21a and the second nameplate portion 21b are fixed to the surface of the upper surface portion 21 by adhesive or the like. When the upper surface part 21 is the above-mentioned striped steel plate, the uneven surface of the striped steel plate is processed into a smooth surface only in the area where the first nameplate part 21a and the second nameplate part 21b are provided, and the first nameplate part 21a and the second nameplate part 21b are The nameplate portion 21b is fixed with adhesive. Alternatively, the first nameplate portion 21a and the second nameplate portion 21b may be adhesively fixed while leaving the uneven surface of the striped steel plate as it is so that the uneven shape appears on the surfaces of the first nameplate portion 21a and the second nameplate portion 21b.

FIG. 7 shows a cross-sectional view of the fire hydrant device 1 cut near the top surface. As shown in this figure, the elastic drive members 32 constituting the drive section 31 are provided at four locations on the main body section 10, and each wire 33 is connected to the four corners of the hose holder 11. Therefore, the four corners of the hose holder 11 can be pulled up by the wires 33, so that the hose holder 11 can be pulled up stably.

FIG. 8 shows a longitudinal sectional view of the fire hydrant device 1 cut near the front with the hose holder 11 pulled up. As shown in this figure, when the wire fixing part 25 of the hose holder 11 is pulled up to the upper part of the main body part 10, the hose holder 11 is prevented from being pulled upward any further by a latch member 26, which will be described later. At this time, almost the entire side portion of the hose holder 11 is exposed above the main body 10, and the front opening 20a and the back opening 20b are also exposed to the outside of the main body 10. In this state, the user can use the fire hose 12 by pulling it out from the road side or the lifeguard passage side.

FIG. 9 shows a perspective view of a state in which the latch member 26 of the hose holder 11 and the latch accommodating portion 36 of the main body 10 are close to each other within the main body 10. The hose holder 11 has a latch member 26 at the bottom. The latch member 26 has a base portion 26a that projects from the hose holder 11 toward the inner surface of the main body portion 10, and a magnet portion 26b that is provided upward at the tip of the base portion 26a.

A box-shaped latch accommodating portion 36 that can accommodate the magnet portion 26b of the latch member 26 is provided on the inner surface of the main body portion 10. The latch housing portion 36 is open downward. As the hose holder 11 rises, the magnet portion 26b of the latch member 26 is accommodated in the latch accommodating portion 36, thereby preventing the hose holder 11 from rising any further. Furthermore, the latch housing portion 36 has a flat portion therein to which the magnet portion 26b is magnetically attracted, and holds the elevated hose holder 11 in its position so as not to descend. The holding force by the magnet part 26b, combined with the biasing force by the elastic drive member 32, is at least greater than the weight of the hose holder 11 with the fire hose 12 filled with water stored in the hose storage part 20. is also set to be large.

In order to smoothly raise the hose holder 11, a guide surface section that extends in the vertical direction is provided inside the main body section 10, and a rotating body that rolls along the guide surface section is provided on the hose holder 11. FIG. 10 shows a cross-sectional view of the fire hydrant device 1 cut near the bottom surface. As shown in this figure, guide surface portions 45, 46, 47, and 48 are arranged at four locations on the main body portion 10. The guide surface parts 45 and 46 face the left and right side directions of the main body part 10. Moreover, the guide surface parts 47 and 48 face the front and back sides of the main body part 10.

Four rotating bodies 40, 41, 42, 43 are provided on the hose holder 11 corresponding to each guide surface portion 45, 46, 47, 48. The rotating bodies 40, 41, 42, 43 are constituted by cam followers. However, the rotating body is not limited to the cam follower, and may be replaced by an LM guide or a slide rail. FIG. 11 shows a perspective view showing the relationship between the guide surface portion 45 and the rotating body 40. As shown in FIG. The rotating body 40 is formed in a columnar shape and is rotatably supported by the hose holder 11. The circumferential surface of the rotating body 40 is in contact with the surface of the guide surface section 45 and can roll on the guide surface section 45 as the hose holder 11 moves up and down.

FIG. 12 shows an enlarged view of the vicinity of the rotating body in FIG. 10. As shown in FIG. 12(a), the rotating body 40 is in contact with the guide surface portion 45 from the right side to the left side in the figure. As shown in FIG. 12(b), another rotating body 41 is in contact with the guide surface portion 46 from the left side to the right side in the figure. Further, as shown in FIG. 12(c), another rotating body 42 is in contact with the guide surface portion 47 from the upper side to the lower side in the figure. Further, another rotating body 43 is in contact with the guide surface portion 48 from the bottom to the top in the figure. In this way, each of the rotating bodies 40, 41, 42, 43 is in contact with the guide surface portions 45, 46, 47, 48 in four different directions.

The tunnel road may have an upslope or a downslope along its length. Further, the tunnel road may have a slope also in the width direction. For this reason, the fire hydrant device 1 provided in the lifeguard passage may be installed to be inclined in either or both of the direction along the length of the road and the direction along the width of the road. Even in such a case, since each of the rotating bodies 40, 41, 42, and 43 is in contact with the guide surface portions 45, 46, 47, and 48 in four different directions, Since at least one of them comes into contact with the guide surface, it can reliably guide the vertical movement of the hose holder 11 by rolling on the guide surface as the hose holder 11 moves up and down. Therefore, stable vertical movement of the hose holder 11 can be ensured.

Next, a structure for preventing the hose holder 11 from falling will be explained. FIG. 13 is a perspective view showing the relationship between the rotating member 50 and the pressing member 51 when the hose holder 11 is being raised. When the hose holder 11 rises, the latch member 26 fixes the hose holder 11 so that it does not fall, as described above, but if a strong impact force is applied to the hose holder 11, the latch member 26 will latch and accommodate the hose holder 11. There is also a possibility that it will be removed from section 36. Even in this case, a structure for preventing the hose holder 11 from falling is provided so that the hose holder 11 can be maintained in an elevated state.

As a structure for preventing the hose holder 11 from falling, a rotating member 50, a stopper portion 52, and an abutment body 53 are provided on the inner surface of the main body portion 10. The rotating member 50 is an elongated plate-shaped member whose one end portion is rotatably supported with respect to the main body portion 10 . The stopper portion 52 is fixed to the inner surface of the main body portion 10, and has a support surface 52a on the upper surface, and a recess 52b is formed in the support surface 52a. The abutting body 53 is fixed to the inner surface of the main body section 10 above the stopper section 52 .

A pressing member 51 is fixed to the hose holder 11 . The pressing member 51 has a fixed surface portion 51a that is fixed to the hose holder 11, and a contact surface portion 51b that comes into contact with the lower surface of the rotating member 50 as the hose holder 11 rises. FIG. 13 shows a state in which the hose holder 11 is raised and the contact surface portion 51b is in contact with the lower surface of the rotating member 50.

FIG. 14 is a perspective view showing the relationship between the rotating member 50 and the pressing member 51 in a state where the hose holder 11 is raised from FIG. 13. As shown in this figure, as the hose holder 11 rises, the pressing member 51 fixed to the hose holder 11 also rises, pushing up the rotating member 50 while rotating it. The rotating member 50 can rotate until it comes into contact with the abutting body 53.

FIG. 15 is a perspective view showing the relationship between the rotating member 50 and the pressing member 51 in a state where the hose holder 11 is raised from FIG. 14. As shown in this figure, when the hose holder 11 further rises, the rotating member 50 loses support from the pressing member 51, rotates under its own weight, and descends to the position of the support surface 52a of the stopper portion 52.

FIG. 16 is a perspective view showing the relationship between the rotating member 50 and the pressing member 51 when the hose holder 11 is lowered after being raised. As shown in this figure, when the hose holder 11 descends after rising to the upper end position, the pressing member 51 also descends, and its lower surface abuts the rotating member 50 supported by the stopper portion 52. As a result, the pressing member 51 cannot descend any further. That is, further fall of the hose holder 11 to which the pressing member 51 is fixed is prevented. In order to minimize the fall of the hose holder 11, the rotating member 50 is arranged at the upper part of the main body part 10.

FIG. 17 is a perspective view showing the relationship between the rotating member 50 and the pressing member 51 when the support jig 54 is attached to the stopper portion 52. When the hose holder 11 rises and pulls out the fire-fighting hose 12, and firefighting is finished, the fire-fighting hose 12 is returned to the hose holder 11, and the hose holder 11 is stored in the main body 10. At this time, the hose holder 11 is lowered from the raised state, but if this continues, the lowering of the hose holder 11 is prevented by the rotary member 50 as shown in FIG. Therefore, as shown in FIG. 17, a rod-shaped support jig 54 is inserted into the recess 52b of the stopper portion 52, and the tip of the support jig 54 supports the rotary member 50 so as to prevent its rotation. Thereby, the pressing member 51 of the hose holder 11 can be lowered without being interfered with by the rotating member 50, and the hose holder 11 can be returned to its original position. When the hose holder 11 returns to its original position, the support jig 54 is removed.

As described above, since the main body part 10 and the hose holder 11 are provided with a fall prevention structure, when the hose holder 11 is pulling out the fire hose 12 that has been raised, the hose holder 11 may unexpectedly descend. This enables reliable firefighting activities.

The configuration of the lock release section 24 will be explained in more detail. FIG. 18 shows a plan view of the handle member 70 having the unlocking portion 24. As shown in FIG. The handle member 70 is a box-shaped member that houses the lock release part 24, and is disposed so that it is embedded in the upper surface part 21 of the main body part 10 so that the lock release part 24 is exposed on the upper surface side.

FIG. 19 shows a sectional view taken along the line AA in FIG. 18. In addition to the lock release part 24, a slide part 71 that can be slid horizontally within the handle member 70 is arranged. The upper surface of the slide portion 71 is in contact with a latch locking portion 75 fixed to the main body portion 10 . As described above, the hose holder 11 is biased upward, and the upward movement of the hose holder 11 is restricted by the upper surface of the slide portion 71 being in contact with the latch locking portion 75. has been done. The latch engaging portion 75 is formed of a member that is rotatable relative to the main body portion 10 at a portion that contacts the slide portion 71 . Specifically, the latch locking portion 75 is formed of a bearing member.

The lock release part 24 is rotatable around a rotating shaft part 24a, and can be operated by inserting a hand from the upper left side in the figure and pulling it up. The lock releasing portion 24 has a pressing portion 24b at its lower end that presses the sliding portion 71 as it rotates. The slide portion 71 has an abutting portion 71a that abuts against the latch engaging portion 75, and a pressed portion 71b that abuts the pressing portion 24b of the lock release portion 24.

FIG. 20 shows a cross-sectional view of the handle member 70 in a state where the lock release part 24 is operated. When the lock release part 24 is rotated around the rotating shaft part 24a, the pressing part 24b presses the pressed part 71a of the slide part 71 toward the left side in the figure, thereby causing the slide part 71 to move toward the left side in the figure. to move the slide. Accordingly, the contact portion 71b of the slide portion 71 moves from the position below the latch locking portion 75, and the upward movement restriction state of the handle member 70 is released. In this state, the hose holder 11 having the handle member 70 is raised by the upward biasing force.

The slide portion 71 before moving is in contact with the latch locking portion 75 under upward pressure, so the sliding resistance when sliding is large, but the latch locking portion 75 is By being rotatable relative to the portion 10, the sliding resistance of sliding movement can be reduced.

FIG. 21 shows a rear view of the handle member 70. The back surface of the handle member 70 into which the hand is inserted is formed by cutting out the area shown by hatching in FIG. 21. The handle member 70 has a concave region in which the lock release portion 24 is housed, and if dust or the like enters this region, it may impede the rotation of the lock release portion 24. By cutting out a part of the back side surface of the handle member 70, it is possible to prevent dust and the like that have entered the concave area in which the lock release part 24 is housed from falling and accumulating in this area.

FIG. 22 shows an enlarged view of the main body 10 with the raised latch handle 29. The rising latch handles 29 have a similar configuration to the handle member 70 provided on the hose holder 11, and are disposed inside the main body 10 at the upper portions of both sides. The hose holder 11 has latch locking portions 76 on both sides of the lower end, and when the hose holder 11 is pulled up to the upper end, the rising latch handle 29 of the main body portion 10 and the latch locking portions 76 are locked. This prevents the hose holder 11 from rising any further.

When the elevated hose holder 11 is to be lowered, it is necessary to operate the ascending latch handle 29 to release the latched state from the latch latching portion 76 . This operation can also be performed by opening the door 30 of the main body 10, but it can only be performed from the road side, and opening the door 30 requires time and effort. In FIG. 22, since openings 16 are provided on both upper surfaces of the main body 10, the user can insert his hand into the main body 10 through the openings 16 and operate the rising latch handle 29. Thereby, the rising latch handle 29 can be operated even from the observer passageway 61 side, and there is no need to open the door portion 30 when operating from the road side, making the work easier.

Although the embodiments of the present invention have been described above, the implementation of the present invention is not limited to this embodiment, and can be applied in various ways within the scope of the technical idea. In this embodiment, the biasing force exerted by the elastic drive member 32 is set to be greater than the weight of the hose holder 11 holding the fire extinguishing hose 12, and the lock engagement portion 23 is engaged with the main body 10. When the hose holder 11 is released, the hose holder 11 is automatically pulled upward by the urging force of the elastic drive member 32. 11, and in the event of a fire, the user may pull up the hose holder 11 with a small force.
